Helly Hansen Odin Infinity Minimalist Jacket review: Featherlight protection for drizzles and downpours

Helly Hansen has made a name for itself in rugged, reliable protection against the elements over the past 150 years, from outfitting Norwegian fishermen in the 1870s to outfitting tens of thousands of ski patrollers and mountain rescue teams across the globe today.

I’ve tested close to a dozen jackets by the brand, including waterproof hiking shells, ski jackets and down jackets, and they’ve nearly always been robust pieces that prioritise warmth and safety over weight and packability.

The Odin Infinity Minimalist Jacket is the first I’ve tested from the brand that’s truly ultra light, and it’s a testament to the time and effort Helly Hansen has put into testing and engineering in-house technologies, with input from mountain professionals.

I’ve been testing this jacket in mixed conditions in the Scottish Highlands and the Lake District, where we’ve been experiencing an even more unpredictable spring than usual, and I currently have it packed and ready to come with me to the Swiss Alps. I’m so impressed that I plan to continue wearing it through the summer and into the autumn.

Helly Hansen Odin Infinity Minimalist Jacket review

Price and availability

The Helly Hansen Odin Infinity Minimalist Jacket is available in men’s and women’s sizing from Helly Hansen for £380 / $400. The women’s design features a drop tail and comes in Ebony and bright Cranberry, which is the colour I tested and is great for making yourself visible on the mountain. The men’s design lacks the drop tail and comes in Ebony, Windy Blue and Ignite Orange.

Compared to the brand’s much more substantial Odin 1 World Waterproof Shell, this price is actually on the reasonable side, but it’s clearly a pricey jacket compared to other lightweight styles from different brands, coming in well above jackets like my Montane Phase Lite and Rab Firewall Alpine.

Design and materials

There are two standout details when it comes to the design of this jacket: its 3.5-layer construction and its ridiculously low weight.

I’ve tested plenty of 2-, 2.5-, and 3-layer rain jackets, but this is the first to go beyond three, and a representative from the brand explained to me that the approach helps increase resistance to water pressure while moving away from traditional, not-so-planet-friendly chemistries.

The 3.5 layers are built in a sandwich method around the brand’s in-house flexible Lifa Infinity waterproof membrane, which features both a non-porous PU layer and a breathable microporous layer underneath – not quite two layers, apparently, but more than one. The face fabric is Helly Tech Professional, and there’s a printed backing on the interior for reinforcement.

With all that, you might expect a thicker, stiffer jacket, but it feels as thin as any 2-layer jacket. I tested the XS, which is as small as it comes, and mine weighs only 180g. That’s lighter than my phone and pretty much every waterproof jacket I’ve ever tested (and I’ve tested many dozens), except for my Rab Phantom running jacket, which is only 2.5 layers in comparison.

The material has four-way stretch, but I don’t notice much, and the cut is quite slim, especially compared to what I’m used to with Helly. Despite that, I find the XS fits me really well and doesn’t feel restrictive anywhere, while I’m still able to wear it over a fleece or light puffer, making it usable for three seasons anyway.

The hood is helmet-compatible, which makes this a contender for blustery days on belay, though I think if I were heading out on a rugged alpine expedition, I’d still want to bring along my Arc’teryx Beta AR jacket.

They’ve also somehow managed to fit a RECCO reflector in the hood without adding much weight, again making this an option for more remote adventures if not ones where you’d be likely to encounter serious weather.

The hem is adjustable, the cuffs are partially elasticated, and there’s a zipped chest pocket big enough for my phone, plus an inner mesh pocket that becomes a handy pouch for packing the jacket away. It even has a loop so it can be clipped to my backpack.

Performance and comfort

This jacket looks and feels very much like a light layer you’d bring along as a “just in case” option, but I’ve worn it through several more sustained and heavy downpours, and one heavy hailstorm, and it largely behaves more like a top-of-the-mountain shell.

In heavy rain, it hasn’t wetted out on me yet, and the only real issue I’ve had with water ingress is that the cuffs do let some water in. I think this is partly down to them not being adjustable, and I think the low-wicking barriers on the cuffs could be wider. It’s also surprisingly windproof for such a thin, light jacket and on early, cold starts, I get instant warmth just by zipping it up.

For such good protection, I’ve been really impressed with the breathability, which is a bit of a unicorn characteristic in true waterproof garments and comes despite a lack of pit zips. I’ve worn it for plenty of milder, dry and sunny hikes, and I’m able to climb with it over a T-shirt and stay quite comfortable, without any clammy buildup on the inside.

The hood is truly excellent, with a collar that protects half my face and keeps it from blowing down. It’s peaked to provide extra face protection without blocking my vision, and it’s easy to cinch snugly around my head.

There are only two pockets on this jacket, but it’s got the one I think is most important: a zipped chest pocket so I can reach my phone even when I’m wearing my backpack (and it’s kept my phone dry in a storm). Considering some ultralight jackets ditch pockets altogether, I’m satisfied with this and personally don’t miss the hand-warming pockets I can’t reach with a backpack on anyway.

Verdict

The Helly Hansen Odin Infinity Minimalist Jacket is a bit of a marvel. It’s rare to find this level of protection at this weight, and I’m planning on getting a lot of use out of it, especially since it’s a layer I’m happy to wear around town as well as on the trail.

Not only does it protect me well against the elements, but it lacks the stiffness I’d usually expect for such a design, and it’s breathable enough to climb in during alpine starts and cooler days.

It’s not perfect, and I think subsequent versions could improve the cuff design, but for a truly packable and light jacket, it’s one of the better options out there (and at this price, it should be).
